I agree that Yahshua (the true and original name of the Savior, not Jesus) spoke through the prophets. Where was the Father? What is the relationship between the Father and the Son? You deny the facts about the Father's name:

The Father is referred to in the Old Testament as the Ancient of Days.
“I watched till thrones were put in place,
And
the Ancient of Days was seated;
His garment was white as snow,
And the hair of His head was like pure wool.
His throne was a fiery flame,
Its wheels a burning fire;
A fiery stream issued
And came forth from before Him.
A thousand thousands ministered to Him;
Ten thousand times ten thousand stood before Him.
The court was seated,
And the books were opened.
Daniel 7:9-10
“I was watching in the night visions,
And behold, One like the Son of Man,
Coming with the clouds of heaven!
He came to the Ancient of Days,
And they brought Him near before Him.
Daniel 7:13
In Revelation He referred to as Him who is seated upon the throne.
And every creature which is in heaven and on the earth and under the earth and such as are in the sea, and all that are in them, I heard saying:
“Blessing and honor and glory and power
Be to
Him who sits on the throne,
And to the Lamb, forever and ever!”
Revelation 5:13
Again, it was Jesus Christ the Son, the Spirit of Christ, the Spirit of the LORD who spoke through the mouth of the prophets… saying thus says the LORD.
Of this salvation the prophets have inquired and searched carefully, who prophesied of the grace that would come to you, searching what, or what manner of time,
the Spirit of Christ who was in them was indicating when He testified beforehand the sufferings of Christ and the glories that would follow. 1 Peter 1:10-11
